Strap for Rolex Cellini 50705RBR

The lug width of the Rolex Cellini 50705RBR is 20mm. This measurement represents the distance between the two lugs where the strap is attached. To verify, position the watch with the lugs parallel to a flat surface and measure from centre to centre between the attachment holes: any strap with a lug-to-lug measurement between 19.8mm and 20.2mm will fit perfectly.

Alligator is the natural choice for the 50705RBR: its fine and regular grain pattern, the patina it develops over time, and its ability to harmonise with rose gold make it ideal. Shell cordovan represents a superior alternative with its density and deep polish. For those preferring aesthetic lightness, vegetable-tanned calf offers a softer surface with a patina that evolves towards deeper tones. Avoid rubber: the Cellini does not deserve it.

You will need two tools: a thin larding knife or a spring bar tool. Position the watch with the strap facing upwards. Locate the small "V"-shaped spring (spring bar) that secures the strap to the lug. Insert the tool tip into the smaller hole of the spring and gently push upwards: the spring will retract. Remove the strap with your other hand. To insert the new strap, repeat the operation in reverse, ensuring that the spring bar clicks securely into its seats.

Yes, any strap with a 20mm lug width is mechanically compatible. However, the Cellini is a dress watch crafted in rose gold with significant luxury elements: it deserves a strap of superior quality, crafted from noble materials such as alligator, shell cordovan or vegetable-tanned calf. The choice of material and colour must respect the formal elegance of the watch, avoiding synthetic materials or sports straps unsuitable to the character of the model.

A high-quality leather strap (alligator, cordovan or superior calf) typically lasts 4-7 years with moderate daily use. Longevity depends on maintenance, climate (humidity accelerates ageing), and frequency of wear. The Cellini is not a sport watch: if worn occasionally (2-3 times per week), a good strap can last 8-12 years. The patina that develops over time is an appreciated characteristic, not a defect. The 18-month warranty on manufacturing defects offered by Casati Milano covers construction flaws, not the natural wear of leather.
